Abstract: Exact analytic calculation shows that optimal control protocols for passive molecular systems often involve rapid variations and discontinuities. However, similar analytic baselines are not generally available for active-matter systems, because it is more difficult to… read more here.

Abstract: Breaking symmetry can give rise to non-reciprocal forces–unequal and opposite forces–typically observed in active matter systems involving asymmetric 2-body interactions. So far, there are few examples of N-body non-reciprocal forces induced by symmetry breaking. Here… read more here.

DOI: 10.3390/e24091198
Abstract: We study the quantum phase diagram and the onset of quantum critical phenomena in a generalized Dicke model that includes collective qubit–qubit interactions. By employing semiclassical techniques, we analyze the corresponding classical energy surfaces, fixed… read more here.
